I was looking at it from a different angle. I think making laws to stop a mob from forming would be very hard, complex, and have lots of hairy side effects. My idea instead is to look at it from an employer's side: one should not be able to fire somebody on the spot for fuzzy PR reasons. So the mob can still form, but the ultimate consequence, a termination, in most cases would be impossible. As to stopping mobs from forming or doing their damage, I strongly believe social networks can do quite a lot too.
